Abstract: We study the actual problem of determining the maximal set for the set of points in $\mathbb R^3$ from the set of two-dimensional projections. This problem arises naturally in the applications of physical hydrodynamics for the optical diagnostics of real flows of liquid and gas by measuring the instantaneous rate fields in the volume of flow. We propose a method for reconstructing the given set and determining the sufficiency of the measurements for the uniqueness of a solution to the inverse problem for parallel and perspective projections. A statistical evaluation for the efficiency of the reconstruction method is obtained.

Keywords: 3D reconstruction of point objects, particle image velocimetry, 3D PTV, inverse problems.
